A gradual increase in noise or vibration during operation is often linked to maintenance or installation factors, rather than a sudden fault.
Common causes include:
Loose fasteners or fixings
Insufficient lubrication
Wear of moving components
An uneven or unstable installation surface
If noise or vibration increases:
Stop the machine safely
Inspect visible fasteners and fixings
Check lubrication levels and points
Confirm the machine is installed on a stable, level surface
Do not continue operation until the cause has been addressed.
Addressing noise or vibration early helps prevent further wear, damage, or unplanned downtime.
